Abstract

PARA EL AUMENTO DE LA ACTIVIDAD CATALITICA DEL CATALIZADOR DE PLACAS LA INVENCION HA PREVISTO, QUE EL CATALIZADOR DE PLACAS COMPRENDA MULTIPLES PLACAS (2,4) RECUBIERTAS CON UNA SUSTANCIA ACTIVA DE FORMA CATALITICA Y DISPUESTA EN UNA UNIDAD CON MEDIOS (6,14,16,20,22) PARA LA DERIVACION DEL MEDIO DE FLUJO A PARTIR DE UNA DIRECCION (12) DE FLUJO PRINCIPAL, AL MENOS PARCIALMENTE DENTRO DEL MISMO ESPACIO (24,26) DE REACCION Y AL MENOS PARCIALMENTE DENTRO DE ESPACIOS (24,26) DE REACCION ADYACENTE. UNA SOLUCION ALTERNATIVA ES SUMINISTRAR MEDIANTE LA DERIVACION DEL MEDIO DE FLUJO AL MENOS PARCIALMENTE A PARTIR DE LA DIRECCION (112) DE FLUJO PRINCIPAL EN AL MENOS UN ESPACIO (106, 136) DE REACCION POR MEDIO DE UNA ESTRUCTURA (108,110,132,134) Y DISPOSICION DE LAS PLACAS (102,104,126,128) O PLACAS (102,104,126,128) ADYACENTES EN RELACION UNAS CON OTRAS. UN ESPACIO DE REACCION ESTA LIMITADO ENTRE CADA UNA DE LAS DOS PLACAS ADYACENTES INMEDIATAS Y LA UNIDAD DE CAJA, QUE ES PERMEABLE AL MEDIO DEL FLUJO,DISPONE DE LADOS DE ENTRADA Y SALIDA DE FLUJO. CON LA TURBULENCIA DE ALTO NIVEL RESULTANTE DEL MEDIO DE FLUJO SE AUMENTA LA CONTRIBUCION INDUCIDA DE GUIA A LA ACTIVAD CATALITICA DEL CATALIZADOR DEL TIPO DE PLACAS. LA INVENCION PUEDE SER UTILIZADA ESENCIALMENTE CON TODOS LOS CATALIZADORES DE TIPO DE PLACAS A TRAVES DE LOS CUALES FLUYE UN MEDIO GASEOSO O LIQUIDO.FOR THE INCREASE OF THE CATALYTIC ACTIVITY OF THE PLATE CATALYST THE INVENTION HAS PROVIDED THAT THE PLATE CATALYST INCLUDE MULTIPLE PLATES (2,4) COVERED WITH AN ACTIVE SUBSTANCE OF CATALYTIC FORM AND DISPOSED IN A UNIT WITH MEANS (6,14,16 , 20,22) FOR THE DERIVATION OF THE FLOW MEDIA FROM A DIRECTION (12) OF MAIN FLOW, AT LEAST PARTIALLY WITHIN THE SAME SPACE (24,26) OF REACTION AND AT LEAST PARTIALLY WITHIN SPACES (24,26) OF ADJACENT REACTION. AN ALTERNATIVE SOLUTION IS TO SUPPLY THROUGH THE DERIVATION OF THE FLOW MEDIA AT LEAST PARTIALLY FROM THE MAIN FLOW DIRECTION (112) IN AT LEAST ONE SPACE (106, 136) OF REACTION THROUGH A STRUCTURE (108,110,132,134) PLATES (102,104,126,128) OR PLATES (102,104,126,128) ADJACENTS IN RELATION TO EACH OTHER. A SPACE OF REACTION IS LIMITED BETWEEN EACH OF THE TWO IMMEDIATE ADJACENT PLATES AND THE CASE UNIT, WHICH IS PERMEABLE IN THE MIDDLE OF THE FLOW, HAS INLET AND OUTLET FLOW SIDES. WITH THE HIGH LEVEL TURBULENCE RESULTING FROM THE FLOW MEDIA, THE INDUCED CONTRIBUTION OF THE GUIDE TO THE CATALYTIC ACTIVITY OF THE PLATE TYPE CATALYST IS INCREASED. THE INVENTION CAN BE ESSENTIALLY USED WITH ALL PLATE TYPE CATALYSTS THROUGH WHICH A GASEOUS OR LIQUID MEDIUM FLOWS.
